What Is The Basic Principle Of A Surge Protector?

Winter brings frequent thunderstorms, especially during heavy rain. Whether indoors or outdoors, it's essential to install surge protective device to prevent various malfunctions and short circuits, which can cause inconvenience. Below is a detailed explanation of the basic principles of surge protectors.

1. Surge protectors are a vital component of lightning protection systems. Formerly known as zinc oxide surge arresters, their function is to limit instantaneous overvoltages introduced into power lines to within the withstand limits of household appliances and various industrial equipment, or to directly conduct excessive voltages to the ground, thus protecting equipment from impact damage.

2. Surge protectors vary in type and construction, leading to differences in their applications. However, at a minimum, they all require a discrete system operating voltage limiting component. Without this component, they are ineffective and useless. In addition, other basic components such as charge/discharge gaps, air discharge tubes, and varistors are also necessary.

3. The function of a surge protection device is to conduct instantaneous overvoltages to the ground or limit them to a level that the machine can withstand, protecting electrical appliances from damage caused by lightning strikes.

Surge protectors include those for switching power supplies. In daily use, people can judge the operating status of the equipment by looking at the indicator lights. Surge protectors have a precise structure, a high installation coefficient, and can perform stably during operation.
